BLADE THRUST IS a reaction that only occurs
when using a bladed unit. This reaction can cause
serious injury such as amputation. Carefully study
this section. If is important that you understand what
causes blade thrust, how you can reduce the chance
of it ocGUm'ng, and how you can remain in;controI of
the unit if blade ihrusf occurs.
WHAT CAUSES BLADE THRUST?
Blade Thnjstcan occurwhen the spinning bladecom
tacts an object ttiat it does not cut. This contact
causes the blade to stop for an instant and then sud­
denly move or “thrust" awayfrom the object that was
hit. The “thrusting” reaction can be violent enough to
cause the operator to be propelled in any direction
and lose control of the unit. The uncontrolled unit can
cause serious injury if the blade contacts the opera­
tor or others.
WHEN DOES BLADE THRUST OCCUR?
Blade thrust can occur without warning if the blade
snags, stalls, or binds. This is more likely to occur in
areas where it is difficult to see the material being cut.
By using the unit properly, the occurrence of blade
thrust m\\ be reduced and the operator will be less
likely to lose control.
The forward tip on the metal blade shield helps to re­
duce the occurrence of blade thrust but cannot pre­
vent the occurrence. The operator must follow ail
warnings and safety instructions in this manual to
lessen the chance of blade thrust occurring and to
maintain control of unit if the reaction does occur.
REDUCE THE CHANCE OF BLADE THRUST
• Cut vegetation up to 2 1/2” diameter saplings with
saw blade.
• Gut only grass, weeds, and woody brush up to 1/2* in
diameterwith the brushtri-blade/Donotletthe blade
contact material it cannot cut such as stumps, rocks,
. fences, metal, etc., or clusters of hard, woody brush
having a diameter greater than 21/2 inches.
• Keep frie blade sharp. A dull blade is more likely to
snag and thrust.
• Cut only at full th rottle. The blade has maximum cut­
ting power at full throttle and is less likely to bind or
stall.
• “Feed” the blade deliberately and not too rapidly. The
blade can thrust away if it is fed too rapidly.
• Cut only from your right to your left.
